Detailed Description

• ID: itg3200
• Name: ITG-3200 3-Axis Digital Gyroscope
• Other Names: Grove 3-Axis Digital Gyroscope
• Category: compass
• Manufacturer: seeed
• Connection: i2c

InvenSense* ITG-3200 is a 3-axis digital gyroscope. (https://www.sparkfun.com/datasheets/Sensors/Gyro/PS-ITG-3200-00-01.4.pdf) This sensor has been tested and can run at either 3.3V or 5V on Intel(R) Galileo.
However, it is incompatible with and not detected on the I2C bus by Intel(R) Edison using the Arduino* breakout board.

        short[] rot;
        float[] ang;

        // Note: Sensor not supported on Intel Edison with Arduino breakout
        upm_itg3200.Itg3200 gyro = new upm_itg3200.Itg3200(0);

        while (true) {
            gyro.update();
            rot = gyro.getRawValues();
            ang = gyro.getRotation();

            System.out.println("Raw Values: X: " + rot[0] + " Y: " + rot[1] + " Z: " + rot[2]);
            System.out.println("Angular Velocities: X: " + ang[0] + " Y: " + ang[1] + " Z: "
                    + ang[2]);

            System.out.println("Temp: " + gyro.getTemperature() + ", Raw: " + gyro.getRawTemp());

            Thread.sleep(1000);
        }

Constructor & Destructor Documentation

Itg3200

(

int

bus

)

Creates an Itg3200 object

Parameters

bus	Number of the used I2C bus

Member Function Documentation

void calibrate

(

)

Calibrates the sensor to 0 on all axes. The sensor needs to be resting for accurate calibration. It takes about 3 seconds and is also called by the constructor on object creation.

short getRawTemp

(

)

Returns an int that contains the raw register value for the temperature

Returns

int Raw temperature

short [] getRawValues

(

)

Returns a pointer to an int[3] that contains raw register values for X, Y, and Z

Returns

int* to an int[3]

float [] getRotation

(

)

Returns a pointer to a float[3] that contains computed rotational speeds (angular velocities)

Returns

float* to a float[3]

float getTemperature

(

)

Returns the temperature reading, in Celsius, from the integrated temperature sensor

Returns

float Temperature in Celsius

int update

(

)

Updates the rotational values and temperature by reading from the I2C bus

Returns

0 if successful
